Introdution

• Application：
• The machine is suitable for slitting various roll materials such as kraft paper,double offset paper,coated paper,self-adhesive,white cardboard, book cover paper,gray board paper,web paper,etc.，and cutting and cutti ng the materials according to different needs in the production process.
• Performance and features：
• The electric braking system of the machine is centrally controlled by P LC.According to the requirements of the cutting process,the cutting para meters are set by the touch screen,and the liquid crystal screen displays the control working state.The control system has the functions of startin g buffer,stopping anti loosening,meter counting and length fixing,and t he operation is very simple：
• The unwinding tension control adopts the full-automatic tension control system to keep the unwinding tension constant,and the taper control can also be realized according to the process requirements：
• The unwinding deviation correction adopts photoelectric automatic devia tion correction system,which can automatically “follow the edge”or “foll ow the line”to ensure the correct feeding position of the substrate：
• The raw material loading and unloading adopts air roof shaftless clampi ng and hydraulic lifting structure （optional lifting structure）；
• The main traction and rewinding are respectively controlled by servo mo tor and driven by frequency conversion.The winding tension is automatical ly controlled by PLC according to the parameters set according to the slit ting process requirements and the change of rewinding diameter；
• The rewinding shaft is an air expansion shaft （optional:slip shaft），a nd the tension is automatically controlled to adapt to the slitting of mul ti coil materials with uneven thickness.
• The unloading device adopts chain type electric loading
